Question 4 (Multiple Choice Worth 1 points)

[08.06 MC]

Which shows 232 - 172 being evaluated using the difference of perfect squares method?

232 - 172 = (529 + 289)(529 - 289) = 196,320

232 - 172 = 529 - 289 = 240

232 - 172 = (23 + 17)(23 - 17) = (40)(6) = 240

232 - 172 = (23 - 17)2 = (6)2 = 36
